BRAKE Application filed January 23, 1930. Serial No. 422,823. 1

This invention aims to provide a brake for a vehicle wheel, the construction being such that the brake may be applied either to the forwarn wheel or to the rear wheel of a vehicle, the brake mechanism being housed within a water-tight drum, so that mud, snow, and rain cannot get to the brake bands, and to the brake drums, with Well-known undesirable results. Another object of the invention is to provide a brake which will run in oil.

and claimed, it being understood that changes may be made in the precise embodiment of f the invention herein disclosed, I Within the scope of what is claimed, without departing from the spirit of the invention.

in the accompanying drawings:

Figure 1 shows in vertical transverse section, a device constructed in accordance with the invention, and applied to the front wheel of an automobile;

Figure 2 is a section on the line 2--2 of Figure 1;

Figure 3 is a section on the line. 33 of Figure 1;

Figure l is a composite perspective showing the beam and attendant parts.

The device forming the subject matter of this application may, of course, be applied either to the front wheel or the rear Wheel of an'automobile, but by way of illustration, in Figure 1, the invention has been shown as applied to a'front wheel, an automobile mechanic being entirely competent to make the necessary changes that will adapt the'de V vice to a rear wheel; I

V The numeral 1 designates, generally, a support, including a steeringknuckle 2 having a neck 8 to' which is connected a disc 1 provided with an outstanding boss 5 from which projects the front aXle6 of an automobile:-

The numeral 7 has been used to designate, generally, a closed casing, made up of a cupshaped body 8 to which a cap plate-9 is attached by securing elements 10. The casing 7 has a plug for the introduction and drainage of oil. The cap plate 9 carries an outwardly extended hub 11, and the front vehicle wheel (not shown) is connected to 'the'casing 7 in any suitable way, through the instrumentality of the hub 11 and the axle 6. The casing 7, therefore, turns'with the automobile wheel. The body 8 of the casing 7 includes a rear wall'38 having an annular flange 39 within which is disposed a pacln'ng 40 located about the disc 4, so that no water or dirtcan get into the'casing 7 at this point. The rim of thebody 8 of the casing 7 is des- OUtGfdIUIIl of the brake mechanism. An

inner drum 14 extends into the body 8 of the V casing 7 and is carried by thecap plate 9.

The numeral 15Inarks a beam or support located within the casing 7. Through the instrumentality of securing elements 16,- the beam '15 is connected to the disc l, which forms part of the support that is designated generally by the numeral 1. On one end of the beam 15 there is a stub shaft 17 supportcam 20 ona shaft 21 mounted to rock in the beam 15. The shaft 21 has an upstanding arm 22 located within the casing 7. A stub shaft 23 is mounted in the beam 15 and on the stub shaft 23 is supported the intermediokr ate portion'of an inner brake shoe 24'that cooperates With the inner drum 14. The stub shafts 17 and 23 are located diametrically opposite to each other; The brake shoe 24 l terminates in eyes 25 inwhich are mounted the prongs 26 of ashaft 27 journaled in the beam 15. An arm 28 is secured to the shaft 27 and is located within thecasing 7.

A tubular shaft 29 is mounted to turn in the disc 4 of the support 1. The shaft 29 may bealluded to as an outer shaft, within which rocks an inner shaft 30 extended through the beam 15. The inner shaft 30 has an arm 31 located Within the casing 7 A link is pivoted to the arm 31 and to the arm 22 of the shaft 21. The tubularor outer tight and liquid-tight within the casing, I

ing 7. The arms 33 and 31 are located on opposite sides of the beam 15. Alink 34 is pivoted to the arm 33 of the shaft 29 and to the arm 28 of the shaft 27. Onthe outer end of the tubular shaft 29 there is an arm 35,

external to the casing 7. On the shaft 30 there .is an arm 36, external to the casing 7.' The arms 35 and 36 are adapted to be I connected to any of the usual means (not ,hicle.

By Way of the arm 35, the tubular shaft 29 may be rotated, and When rotation is imparted to the tubular shaft 29, the arm 33 will act through the link 34 and the arm '28 to rock the shaft 27, the prongs 7 26 01. the fork of the shaft 27 coacting With the eyes 25 on the inner brake shoe 24 to con- 'tract the inner brake shoe about the inner brake drum 14, which turns in oil, the level I of the v oil being indicated by .the numeral 51 in Figure 1.
